TECHNICAL FIELD

The application relates generally to an addressing system for a wireless communication network.

BACKGROUND

A node identity (ID) is used to identify a transmitter of data as well as a receiver of data in any radio technology that requires a frequent signalling of node identities in packet transmissions. The node ID, which is set as a receiver ID of data packet, is used to separate transmissions at the receiver from each other, i.e. the receiver should act only on messages intendent for it. The node ID, which is set as a transmitter ID of data packet, is used to identify the transmitter so that the receiver can perform correct actions towards the transmitter.

In wireless communication systems, such as Bluetooth Low Energy (BLE) networks and Wireless Local Area networks (WLAN), e.g. Wi-Fi networks, where different devices can independently access to a channel and transmit packets, there is need to include both receiver ID and transmitter ID into each packet transmission.

The node ID needs to be long enough, i.e. number of bits, to provide at least a local uniqueness of transmitter and receiver, which is transmitted in every packet transmission. This can be e.g. 32 or 48 bits, where 48 bits can already provide global uniqueness with 2{circumflex over ( )}48 addresses.

The BLE system uses 48 bits-long receiver and transmitter IDs (addresses) in a Medium Access Control (MAC) header of packet after a Physical layer (PHY) header of packet. In a WLAN (Wi-Fi) system, for one, each packet contains a Basic service set (BSS) ID as well as 48 bits-long transmitter and receiver IDs that are in its MAC header. This leads to a very brute-forced packet solution where each transmission in the WLAN system contains the 48 bits-long BSS ID, 48 bits-long receiver MAC address, and 48 bits-long transmitter MAC address.

Such bit sequence for the receiver and transmitter IDs at each packet transmission is considerable amount of overhead, especially, when data transmissions are sufficiently small, which can be the case in Internet of Things (IoT) operation. For example, if a data amount, transmitted by an IoT device as single data burst, is 32 bytes, resulting that if it is used 32-48 bits both receiver and transmitter IDs in each of the packet transmission, these IDs introduce 25%-37.5% overhead.

DETAILED DESCRIPTION OF THE FIGURES

FIG. 1 presents an environment, wherein an addressing system 100 may be applied.

The environment comprises a wireless communication network (system) 102, which comprises a plurality of wireless communication devices (nodes) 104, 104 a, 104 b. The devices 104, 104 a, 104 b operate on a same spectrum at a same geographical area, e.g. within the example environment. The usage of same spectrum enable a bi-directional communication is between the devices 104, 104 a, 104 b, i.e. radio transmissions transmitted by one device 104, 104 a, 104 b of network 102 may be received by another device 104, 104 a, 104 b of network 102 and vice versa.

The system 100 may be applied to any wireless communication network 102 that uses frequent signaling of node identifiers (identities, IDs) in packet transmissions. Preferably, the system 100 may be applied in wireless communication networks 102 complying DECT (Digital European Cordless Telecommunications)-2020 standard. Some non-limiting examples to which the system 100 may be applied may comprise, but is not limited to, BLE mesh network, Thread network, Zigbee network, Public Land Mobile Network (PLMN), WLAN network, cellular network, or wireless mesh network, e.g. wireless sensor network, and/or any other wireless networks.

Typically, the devices 104, 104 a, 104 b of the network 102 are capable to receive transmissions with one radio technology, e.g. BLE transmissions or WLAN transmissions, which transmissions are all from the same network 102. However, at least one of the devices 104, 104 a, 104 b of network 102 may be capable to receive transmissions with at least two radio technologies, e.g. BLE transmissions and WLAN transmissions, which transmissions are all from the same network 102.

The DECT-2020 is radio access technology developed by ETSI. The DECT-2020 supports massive machine-type communication (mMTC) and ultra-reliable low latency communication (URLLC). On Physical (PHY) layer, the key technology components of the DECT-2020 are Orthogonal frequency-division multiplexing (OFDM), adaptive modulation and coding schemes (MCS), Modern Channel coding methods (Turbo, LDPC, Convolutional coding), HARQ for both scheduled and contention based transmissions, and a support of multi-antenna transmissions with different Multiple-Input and Multiple-Output (MIMO) streams. On Medium access (MAC) layer and from system aspects, the key technology components of the DECT-2020 are a support of high number of IoT sensors, actuators, and other industrial applications; support of Mesh network topology, support of URLLC communication with very short delay (typical application may be wireless microphones); operation on frequencies that are license exempt; and support of multiple overlapping non-coordinated networks with cognitive radio capabilities to share spectrum resources between multiple networks.

FIG. 2 a presents an example format of packet 208 that is used in the system 100. The system 100 is not limited to this packet format and, naturally, any other format may be used.

The packet 208 may be, but is not limited to, a PHY layer packet 208 as presented in the figure.

The format of packet 208 comprises fields of Synchronization Training Field Symbols (STFS) 210, channel training field (CTF) 212, PHY header field, i.e. PHY control field (part), 214, and data field 216. The STFS field 210 is used to provide time and frequency synchronization for the receiving device 104, 104 a, 104 b and, additionally, it may be used to other purposes, such as adjusting gain of the receiving device 104, 104 a, 104 b. The CTF field 212 is used for channel estimation purposes in the receiving device 104, 104 a, 104 b. The header field 214 is used to transmit necessary information how the data field 216 is transmitted. The header field 214 may comprise, but is not limited to, information used Modulation and coding scheme (MCS), a network address (identity, identifier, ID) a receiver address (identity, identifier, ID), a transmitter address (identity, identifier, ID), a transmission power used to transmit the packet 208, a HARQ process number, a new data indicator, a redundancy version of the packet 208 and/or a HARQ feedback information. The data field 216 comprises at least one MAC protocol data unit (PDU) and it is the field that is re-transmitted in a HARQ operation.

The header field 214 comprise identification information, i.e. a transmitter identifier, representing (identifying) the transmitter (transmitting device) 104, 104 a, 104 b. Alternatively, or additionally, the header field 214 may further comprise identification information, i.e. a receiver identifier, representing (identifying) the receiver (receiving device) 104, 104 a, 104 b. The header field 214 may be protected with Cyclic Redundant Check (CRC) so that receiving device 104, 104 a, 104 b may ensure that reception of the header field 214 was correct. The length of the CRC in the header field 214 may be e.g. 8 or 16 bits.

The length of the header field 214 may be 26-120 bits, even though other lengths of header field 214 are possible. Preferably, the length of header field 214 may be approx. 50-80 bits and it may depend on the format of the packet 208. Alternatively, or additionally, the length of header field 214 may depend on whether the CTF field may be used to transfer control channel bits or not. Above, it is discussed about the length of header field 214, but the same applies also to the header field 214 of the packet 208, if the packet 208 is packet of any other layer.

FIG. 2 b presents an example of a MAC PDU structure 218 that is used in the system 100. The system 100 is not limited to this structure and any structure may be used.

The MAC PDU structure 218 comprises, a MAC header field, and at least one parts of MAC PDU data. The MAC header field is used to indicate the content of the MAC PDU data to the receiving device 104, 104 a, 104 b as well as convey necessary parameters of a MAC level security (when used). The MAC level security is expected to cipher all other fields of the MAC PDU expect the MAC header field, whereas an integrity protection may be provided with a message integrity code (MIC) from the complete MAC PDU and added to end of the MAC PDU.

FIG. 3 presents how an addressing method 320 is used in the transmissions of previously described packets 208, and how devices 104, 104 a, 104 b operate in the previously described system and network 100, 102.

The method 320 is described mainly by using two devices 104 a, 104 b, i.e. a first device 104 a and a second device 104 b, both belonging to the same network 102, which may also comprise a plurality of other devices 104.

At a step 322, each device 104, 104 a, 104 b of the network 102 presents, by means of its controller part 424, a long node identifier (long ID, long address) L-ID, which may be e.g. 32-48 bits long identifier, e.g. a 48-bits Ethernet MAC address used in Wi-Fi networks. The presented L-ID is globally unique, or unique at least in the network 102, wherein the device 104, 104 a, 104 b operates or prefers to operate.

Each device 104, 104 a, 104 b is able to provide, by means of its data transfer part 426, the bi-directional radio communication with at least one other device 104, 104 a, 104 b, i.e. to transmit at least one data packet 208 to other device(s) 104, 104 a, 104 b and to receive at least one data packet 208 from the other device(s) 104, 104 a, 104 b, in the network 102 as previously has been described. In other words, each device 104, 104 a, 104 b may act as a transmitter and/or as a receiver.

In the method 320, the device 104 a is acting as a transmitter and the device 104 b is acting as receiver at the start and these roles change between the devices 104 a, 104 b during their mutual communication. Preferably, the transmitter and the receiver devices 104, 104 a, 104 b may be identical with each other. However, the invention is not limited to that.

This presented L-ID of each 104, 104 a, 104 b identifies (address) the device 104, 104 a, 104 b from other devices 104, 104 a, 104 b, which operate in the network 102, and it is used in at least one security procedure, e.g. in the ciphering and/or integrity protection, of communicated data in the network 102.

At a step 328, each device 104, 104 a, 104 b generates (allocates), by means of its controller part 424, when it intends to initiate an association with other device 104, 104 a, 104 b in the network 102 in order to communicate with it or with the network 102 in order to join it, a random short node identifier (short ID, short ad-dress)S-ID, which may be e.g. 8-32 bits long identifier. The S-ID is generated so that it is shorter than the L-ID, which means that it comprises fewer bits than the L-ID. The S-ID may be e.g. 8, 16, 24, or 32 bits long, but in the DECT-2020, it is preferably 16 or 24 bits long.

The generated S-ID of each 104, 104 a, 104 b identifies and differentiates the device 104, 104 a, 104 b from other devices 104, 104 a, 104 b in a dedicated communication (association), e.g. a unique packet transmission, between two devices 104, 104 a, 104 b in the network 102.

When each device 104, 104 a, 104 b has its L-ID and one of devices 104, 104 a, 104 b, which is in this example a device 104 a, wants to initiate an association with at least one other device 104, 104 b in the network 102 and to communicate with it, the device 104 a generates the random S-ID for itself.

At a step 330, the device 104 a determines a beacon packet 208. It includes, by means of its controller part 424, the generated S-ID as a transmitter address into a control part (field) 214, e.g. a PHY control field, of beacon packet 208 to be broadcasted and its L-ID as a plain text into another part (field), e.g. data field 216, of beacon packet 208 in order to secure the packet 208. The beacon packet 208 is broadcasted to all devices 104, 104 b or a certain group of devices 104, 104 b in the network 102, whereupon this is also indicated in the control part 214 (as a “receiver address”). A rest of packet 208 may be ciphered and integrity protected or sent as a plain text. Then, the device 104 a starts to broadcast, by means of its data transfer part 426, the generated beacon packet 208 to which has been included both the S-ID and L-ID as an intention to associate with other device(s) 104, 104 b.

The usage of 8-32 bits long S-ID reduces the overhead of transmission at the control part 214 of packets 208. Especially, in packets 208 using substantially short slots, the overhead of control part 214 may be minimized in order to use the short slots efficiently for application layer data. For example, the DECT-2020 supports 1.728 MHz channel bandwidth with 27 kHz subcarrier spacing with only slot length of 10 ms/24=0.41666 ms, i.e. a packet (frame) time is 10 ms and the packet is split into 24 time slots.

When the device 104 a broadcasts its beacon packet 208, it may detect, by means of its data transfer part 426, the environment at the same time in order to listen a radio communication of the other devices 104, 104 b and to receive beacon packets 208 from the other device(s) 104, 104 b similarly as these other devices 104, 104 a operate. During these operations, it detects, by means of its controller part 424, S-IDs included into a control part 214 of detected communication packets 208 and records (stores) the detected S-IDs, by means of its controller part 424, into its memory part 432.

Each of other devices 104, 104 b also operate similarly, i.e. those listen the radio communication of the other devices 104, 104 a in the network 102 and checks, by means of the controller part 424, whether any of detected S-IDs of the other devices 104, 104 a is similar to its own S-ID.

At a step 334, when one of the other devices 104, 104 b, which is in this example a device 104 b, receives, by means of its data transfer part 426, the broadcasted beacon packet 208 from the device 104 a, it detects, by means of the controller part 424, the S-ID of device 104 a from the control part 214 of received beacon packet 208, and checks, by means of its controller part 424, whether the included S-ID of device 104 a is similar to its own S-ID or to any other recorded S-ID, which the device 104 b already knows.

At a step 336, if such coincidence exists, i.e. the device 104 b detects that the received S-ID of device 104 a is similar to its S-ID, the device 104 b re-generates (reallocates) a new S-ID for itself similarly as described in the step 328 and returns to listen its environment.

At a step 338, if such coincidence does not exist, the device 104 b, which also has now detected the L-ID of device 104 a from the data part 216 of beacon packet 208 and which intends to associate to the device 104 a, determines, by means of its controller part 424, an association request packet 208. The device 104 b includes its S-ID as a transmitter address and the S-ID of device 104 a as a receiver address into a control part 214 of association request packet 208. The device 104 b also includes at least its L-ID as a plain text into another part, e.g. a data part 216, of association request packet 208. A rest of packet 208 is ciphered and integrity protected. The device 104 b may also include the L-ID of device 104 a into the data part 216. Then, after the determination of association request packet 208, the device 104 b transmits (an unicast transmission), by means of its data transfer part 426, it to device 104 a.

At a step 340, when the device 104 a receives, by means of its data transfer part 426, the association request packet 208 from the device 104 b, it detects, by means of the controller part 424, the S-ID of device 104 b from the control part 214 of received association request packet 208 and checks, by means of the controller part 424, whether the included S-ID of device 104 b is similar to its own S-ID or to any other recorded S-ID, which the device 104 a already knows.

At a step 342, if such coincidence exists, i.e. the device 104 a detects that the received S-ID of device 104 b is similar to its or some other recorded S-ID, the device 104 a determines, by means of its controller part 424, an association non-acknowledged (NACK) response packet 208. The device 104 a includes its S-ID as a transmitter address and the S-ID of device 104 b as a receiver address into a control part 214 of NACK response packet 208, and, then, transmits, by the data transfer part 426, the NACK response packet 208 to the device 104 b.

At a step 343, after the device 104 b has received the NACK response packet 208, the device 104 b re-generates a new S-ID for itself similarly as described in the steps 328, 336, and returns to determine a new association request packet 208 by means of its new S-ID and re-transmit it similarly as described in the step 338.

At a step 344, if such coincidence does not exist, the device 104 a, which also has now detected the L-ID of device 104 b from the data part 216 of association request packet 208 and intends to associate with the device 104 b, determines, by means of its controller part 424, an association acknowledged (ACK) response packet 208. The device 104 a includes its S-ID as a transmitter address and the S-ID of device 104 b as a receiver address into a control part 214 of ACK response packet 208, and, then, transmits, by the data transfer part 426, the ACK response packet 208 to the device 104 b in order to complete the association. The device 104 a may also include at least one of the L-IDs of devices 104 a, 104 b into another part, e.g. a data part 216, of ACK response packet 208.

The previously-described association signalling between the devices 104 a, 104 b is used to exchange the relation of L-ID and S-ID, whereupon the HARQ operation is enabled at link layer with the S-ID as well as the ciphering and integrity protection with using the L-ID.

At a step 346, after the completion of association, before the device 104 a receives a data packet 208 from the device 104 b, the device 104 b includes its S-ID in the control part 214 of data packet 208 as a transmitter address and the S-ID of device 104 a as receiver address. The security procedures of data packet 208 are done by using the L-ID of the device 104 b or using the L-IDs of both devices 104 a, 104 b. The device 104 b performs the security procedures by using the L-ID of device 104 b in chipering mask and integrity protection calculations (calculation of MIC), but it may not include the L-ID of either device 104 b or device 104 a.

When the device 104 a receives the data packet 208, the device 104 a uses the S-ID of device 104 b obtained from the control part 214 of data packet 208 to obtain the correct L-ID of device 104 b and it performs an unciphering and integrity protection check by using the L-ID of device 104 b, or by using the L-IDs of both devices 104 a, 104 b. The device 104 b has obtained the correct S-ID-to-L-ID relation information at the association-completed step 344 as previously has been described.

The roles of devices 104 a, 104 b may naturally be vice versa.

Without the correct S-ID-to-L-ID relation information the integrity protection fails and the data packet 208 is discarded. Thus, the transmission of L-IDs over radio interface is avoided. Even if other communication pair of devices 104 uses the same S-IDs than the devices 104 a and 104 b, and 104 b receives such a data packet, the data will not be incorrectly forwarded to higher layers.

The communication between the devices 104 a, 104 b by packet transmissions exists as long as the association has not terminated. The termination may be performed by a termination packet 208 that terminates the association or it may occur when the communication between the devices 104 a, 104 b has been suspended for some reason, e.g. due to a lack of communication during a predetermined time period.

The generation of S-IDs provides the system 100, where each device 104, 104 a, 104 b has two independent identifiers when the L-ID provides network wide uniqueness and the S-ID provides local link-level uniqueness in its radio neighborhood. The L-ID is used as a basis of link layer security procedures, e.g. ciphering and integrity protection, and in mesh network operations for packet routing.

FIG. 4 presents a device 104, 104 a, 104 b that is able to communicate in the network 102 and to perform the addressing method 320.

The device 104, 104 a, 104 b comprises the controller (control) part 424 that controls operations of its parts 426, 432, 448, 450, 452 so that the device 104, 104 a, 104 b operates as described in the context of previous figures.

The controller part 424 comprises a processor part 448 that performs operator-initiated and/or computer program-initiated instructions, and processes data in order to run applications. The processor part 448 may comprise at least one processor, e.g. one, two, three, or more processors.

The controller part 424 also comprises the memory part 432 in order to store and to maintain data. The data may be instructions, computer programs, and data files. The memory part 432 comprises at least one memory, e.g. one, two, three, or more memories.

The device 104, 104 a, 104 b also comprises the data transfer part 426 and an antenna part 450 that the controller part 424 uses in order to send commands, requests, and data to at least one of entities in the system 100, e.g. devices 104, 104, 104 b, via the antenna part 450. The data transfer part 426 also receives commands, requests, and data from at least one of entities in the system 100, e.g. devices 104, 104, 104 b, via the antenna part 450. The communication between the data transfer part 426 of device 104, 104, 104 b and other entities in the system 100 is provided through the antenna part 450 wirelessly.

The device 104, 104 a, 104 b also comprises a power supply part 452. The power supply part 452 comprises components for powering the device 104, 104 a, 104 b, e.g. a battery and a regulator.

The memory part 432 stores at least a data transfer application 454 for operating (controlling) the data transfer part 426, an antenna application 456 for operating the antenna part 450, and a power supply application 458 for operating the power supply part 452.
